Be it known t at I, EMIL' ANDERsoN', a

lcitizen of the United States of America, and

a resident of Brooklyn, county of Kings, and State of New York,` have invented certain fnew and useful Improvements in Condenser Pumps, ofwhich the following is a speciiication, reference being had to the acc0mforming a part thereof. 4invention relates to i provenfents in con enser pumps and its object is to rovide appa-` which comprises its own motor and may be directly -aiiixed to a condenser ratus which well. t

The advantages of this invention will ap#vv pear in the following speci cation in which I will describe an apparatus built according to the present invention, the novel features of .which will be set forth in appended Referring to the drawingsigure l is a side elevation of .a condenser of ordinary-construction with a pump made according to my invention connected there'- e condenser is drawn in section to clearly'show the way my novel apparatusis associated with it.

In" Figure 2 'the condenser well and my pump are shown in sectional side elevation. ,f

Figures 3, 4 and 5 are sectional plan views sections in these figures belng taken respectively on the lines 3-3, 4 4 .and 5-5 of Figure 2. l

An enlarged sectional side elevation of a lportion of the motor is shown in Figure 6 and a plan view' of a. is shown inFi ure 7.

Certain details of construction are shown in Figure 8, this. ligure showing in sectional end elevation one of the thin corrugated part of the rotor-ring rings of the rotor, the' section being taken on the rotor ring is shown in view in Figure 10,'the view in this case being taken on the line l0j10 of/Figure 9.

Like parts are designated bythe same reference charactersin all' of the figures.,.

stantially lcoarial i therewith. Dported by a'sp'ider37 which overhangsjthe lin itselowe'r end, which Vforms a improved condenser pump may be utilized with any of the well known forms of condensers, such as, for example, that shown in Figure l'whichcomprises a tank 15 having water-heads 16 and 16 with an inlet' 17 and an outlet 18, a plurality of pipes or tubes 19 connecting the water-heads, a steam inlet 20 and a hot w'ellf21 which receives the condensed steam.

The hot well is shown on a larger Scale in Figure2 and it is to thisl part of the condenser that lmy improved pum l is attached. As clearly indicated in the dliawings, the pump and its motor occupy a very small amount of space and since this apparatus is also efficient in operation, it possesses decided advantages over those hitherto available for this service. The pump comprises a stf'itionary'v frame 22' composed off two parts 23 `and 24, a' shaft 25, an engine or driving rotor 26, and aj pumping rotor 2, both rotors being aHiXed to the shaft 25.

The condenser well 21 has a hole 28 and the part 23 of the frame 22 has a hollow c lindrical projection 29 which extends t in position by a lange 30 which is bolted or otherwise secured to. the well. Within rough the hole into the well and'is held the. hollow cylindrical; projection 29 isa sleeve valve 31 which, 1s vertically adjustyable andis automatically controlled by .a

lever 32 having a float 33 at onelend. The lever 32 ispivoted at 34 upon an upwardly projecting ear` 35 of a stationary tubular member 36, which is within the sleeve valve 31. The tubular member' 36 is .materially smaller than the sleevevalv, and' is sub- It4 is suptrop of the sleeve valve and has Supporting legs 38 which extend to the' bottom of the hot well. 1

The tubular-member 36 lhas a'ilange 39 part of a partition wall 40 within the frame 23.1 This partition Wall is interrupted by an annular opening 41 intowhich the annular. rotor rin 27 of the, pump extends.

lgetween the frame a partition wall 42- havinga bearing 43 for the shaft 25, another guide bearing 44 for the same shaft, being l section 24. A suspension bracket 45 supports a frictionless hrust bearing 46 of any suitable character, hich carries the wei lit provided in the frame Sections 23 and 24 is of the 'shaft and of the rotating parts which are secured to it. `The pump rotor 27 com-` prises a .disc 47 having a hub -48 and the roto-r.ring 27 which is shown 1n detail 1n Figure 9 and comprises spaced rings 49, 5() and 51, one set of buckets 52 between the plates 49 and 50 and a second set of buckets 53 between the plates 50 and 51. The passages between the buckets 52 which are clearly shown in Figure 5, are sub-divided by rings54 and the passages between the buckets 53 are sub-divided into a relatively large number of wavy passages by rings .55 having wavy sections. The buckets are built up of curved lspacing plates (see Figure 8) interposed between the rings,` and the rotor ring is bolted vor-otherwise secured to the disc 47. y s

' The pump rotor extends axially through the opening 41 i-n the partition 40 so that the intermediate ring 50 fits closely into the openingJ and' constitutes a continuation of the wall, filling the gap between `the flange 39 and the outer portionof the wall. As clearly shown inlFigureA 2 the pump rotor is disposed Vin the space between the partition wall 4() and the partition wall 42 near the upper end of 'the shaft 25.

Between the partition wall 42 and the bottom frame of section 24 is disposed the driving engine or motor which comprises a stationary member 56 havin a nozzle section` 57, and the rotor. 26 w ich comprises a plate 58 having -a hub 59 and a rotor ring 60l which is shown on a larger scale in Figures 6 and 7. This rotor ring is preferably formed in accordance with my co-pending application, Serial No. 724,516, filed October 8, 1912 and comprises a pair of spaced rings 61 having buckets 62 between them, the passages being sub-divided4 by rings 63 having 'wavy portions between buckets and the buckets being composed of curved spacers as in the pump.

Motive Vfluid is admitted through an in- -let opening 64`into the nozzle/section 57 and is discharged from the nozzle through l `the wavy passages between buckets 6,2, and `:finally is exhausted through 'the outlet opening 65. y s t l The ub lar member 36 is preferably providedkwith holes 70 abouty on the level of l the bottom ofthe well 21 and extends upwardly above the top of the sleeve valve 31 and hence above the maximum level of water'in the well. The. sleeve valve has ear projections 71 and is connected to the lever 32 by a bail 72 which serves as a link to connect the parts. The lever 32 has a weight 73 .at the opposite end from the float 33, whlch acts as a counter-weight and substanl tially balances the weight of the sleeve so that it is easily raised and lowered in response to variations in the level of theliquid in the well.V` The interior of the tubular member 36,constitutes an air passagle from which air is continually being ex austed by that part of the pump which is composed of the buckets 53 and the wavy plates 55. An annular passage 74 is provided between the tubular member 36 and the sleeve valve 31 through which liquid is conducted to the other section of the pump comprised of the buckets 52.

As already explained, the passages between these buckets are sub-divided by the rings 54 and the arrangement of parts is such that one or more of these passages may be opened and closed by the automatic adjustment ofthe sleeve valve 31. The level of the water in the well may thus be prev entedV from becoming so low as to permit air vto `flow backwardly through the water outlet while it is, at the same time, prevented from rising beyond a certain maximum by reason of the activity of the pump.

It is thus evident that the pump 1n operation serves the double purpose of exhausting the air from the condenser and of draining the water from the condenser well.

The pump preferably operates at a high speed and the engine or motor which is shown as attached to it, is well calculated to perform this function and to drive thc pump at such speeds as to render the operation of the entire apparatus highly efficient.

Securedto the shaft 25 below the bear- 'ing 44 is a worm wheel 75 which meshes with a worm gear 76 on a governor shaft 77, a governor o any well known form, such as, for example, a fly ball governor 78, is mounted on the governor shaft and is adapted to close a throttle valve 79 if the speed of the engine and pump exceeds a predetermined value. The holes in the tubular member 36 may be larger or smaller dependent upon the desired amount of moisture preferably supplied to the air and forced outwardly through the wavy passages between the buckets 53. The apparatus is, of course, operative if there are no holes in the sleeve but the vacuum atltamable is not as high as that which. may

be secured in the condenser by permitting l a certain amount of `water to be mixed with the air as it is pumped out.

Of course, the quantity of water may be Aincreased indefinitely, andr in fact all of the water from the well may pass directly into the tubular member 36 and be forced out through the wavy passages with the air. The sleeve 31i would then be superfluous and could be entirely omitted, but with this arrangement the power required to drive the pump is very materially increased, and consequently I prefer to utilize the structure illustrated in which the bulk of the water is forced out through the straight passages between the buckets 52 only a small amount of moisture being carried withthe vbe permitted to escape into the yanatra i air through `the buckets 53.

The water which is discharged from the pump outlet 8O iswarm and may be supplied to the boilers ofthe systemof which the condenser forms apart. The steam discharged through the passa e erably mixed with the water' sage 80 in order to condense the-steam and transfer its head to the water. yThe moist air discharged from, theair passage 81 will Vatmos here. paratus will be wavy passages Abetween .the`

rom the pas- Tlie operation of the a clearly understood from t e foregoing description, and will now be outlined as -fol lows: Assuming that the driving en e is operating at a high -speed and is riving the pump at a corresponding speed, if'thev level of the water in the well is as indicated in Figure 2, it will gradually fiow over the top of the sleevevalve 31 llin'g the passage pumping action of the buckets52. Asthe` level of the water in the well falls, the `float 33 will move downwardly carrying the lever 32 and the sleevevalve 31 with it, hence water will be continuously suppliedto the assage `h 74 and to the pump until the water evel in the well becomes relatively low. Then the lower end offthe sleeve valve 31 will have moved downwardly so as to close one or more of thepassages between the lates 54 thereby reducing the capacity of tlie water pump,A

and if the condenser is assumed ,to be continu be raised. Thus as aresindicated in the ously in service,- the'` water in the well will increase and cause the sleeve valve to again the amount of waterv delivered' by the pump is automatically determined by the is designed to take care ofthe maximum condensation inthe condenser. v

At thev same timethe airis drawn through is forced out. wardly through the' wavy passages between" the plates 55. f
